Yes you can.

I had my own 14 Pro Max battery replaced about two months ago at an Apple store while I went to a “long lunch.”

Store told me to come back in 2-Hours; it was ready for pickup in 90-minutes.

Cost was about $100.

Just a note to point out that it would be wise to confirm with the shop before you bring the iPhone in to make sure that they have the battery that you will need in stock.

Otherwise, it will be a few days before the battery arrives.

Mr Timmons is spot-on w/ his recommendation.

Using the link provided to actually “book” a Battery Service Appointment helps ensure that all the required parts AND the right technician(s) are on-hand when you show up for your appointment …

… or be notified in-advance if there’s a delay.
